The $675 million jackpot will be the biggest in U.S. history, topping a March 2012 jackpot of $656 million.

The grand prize hit $400 million over the weekend after another winner-less drawing on Saturday, and then hit $450 million on Tuesday. It climbed another $50 million since Tuesday morning, according to lottery officials.

An estimated 300 million new tickets purchased between Sunday and Wednesday.

"This is more than 10 times what we see when the jackpot is at the lower levels," Texas Lottery spokesperson Kelly Cripe said Tuesday when it stood at $450 million.

Nobody has matched all six numbers in one of the bi-weekly Powerball drawings since Nov. 7, 2015. That's 17 drawings with no winner.

Powerball is sold in 44 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands.
